Risk factors for readmission after initial diagnosis in children with acute lymphoblastic leukemia

Early Discharge of Adolescent and Young Adult Patients During Induction Chemotherapy for Newly Diagnosed Acute Lymphoblastic Leukemia: Is It Safe?

There is a lack of consensus for safely discharging adolescent and young adults (AYA) with newly diagnosed acute lymphoblastic leukemia. From 2017 to 2019 we evaluated predefined early discharge criteria for 41 AYA patients during induction chemotherapy. Only 17% (7/41) of patients met criteria for early discharge. Two (29%) patients who were discharged early were readmitted, but not to the pediatric intensive care unit (PICU). This outcome was compared to a historic cohort at our institution of 73 patients who were discharged without predefined discharge criteria. Twenty-seven (37%, p = 0.7) patients were readmitted, but 13 (48%) were readmitted to the PICU (p = 0.004).

Readmission after hospitalization with Staphylococcus aureus bacteremia in children

BACKGROUND

Readmission rate is an important quality measure and can inform patient care. However, readmission of S. aureus bacteremia in children requires further research.

METHODS

We performed a population-based longitudinal observational study using the State Inpatient Database from New York, Florida, and Washington, 2009-2015. Children aged 18 years or younger hospitalized with S. aureus bacteremia were included. The outcome of non-elective readmission was assessed by developing Cox proportional hazards regression models.

RESULTS

Of 1240 children with S. aureus bacteremia, 223 (18.0%) and 351 (28.3%) had non-elective readmission within 30 days and 90 days after discharge, respectively. On multivariable analysis, catheter related infection (hazard ratio, HR: 1.79, 95% confidence interval, CI: 1.31-2.45) was associated with 30-day readmission. The median cost of the original hospitalization for S. aureus bacteremia was $29 914 (interquartile range, IQR: $13 276-$71 284), and that of 30 day readmission was $10 956 (IQR: $5765-$24 753).

CONCLUSIONS

S. aureus bacteremia is associated with a high rate of readmission in children, particularly in those with catheter related infection. Hospitalization with S. aureus bacteremia and readmission are costly. Future research should seek interventions to improve outcomes of S. aureus bacteremia in children, and the results of this study can serve as a benchmark.

Predictors for early readmission in patients hospitalized with new onset pediatric lupus nephritis

OBJECTIVE

The objective is to determine the 30-day hospital readmission rate following a hospitalization due to pediatric lupus nephritis of recent onset and characterize the risk factors associated with these early readmissions.

METHODS

The study included 76 children hospitalized from 01/01/2008 to 4/30/2017 due to a new diagnosis of lupus nephritis. We calculated the 30-day hospital readmission rate and compared the characteristics of the patients that were readmitted to patients that were not readmitted using univariable and multivariable analysis.

RESULTS

The 30-day readmission rate was 17.1%. Factors that predicted hospital readmission in unavailable analysis were male gender (38.5 vs 14.3%, p = 0.04), not receiving pulse steroids (30.8 vs 3.2%, p = < .001), receiving diuretic treatment (69.2 vs 34.9%, p = .02), receiving albumin infusions (46.2 vs 12.7%, p = .004), stage 2 hypertension on day one of admission (76.9 vs 41.3%, p = .02), a higher white blood cell count on discharge (13.7 × 10³/mm³ vs 8.8 × 10³/mm3^, p = .023), need for non-angiotensin converting enzyme (ACE) antihypertensive drugs (76.9 vs 46%, p = .042), and being discharged on nonsteroidal anti-inflammatory drugs (NSAIDs) (23.1 vs 4.8%, p = .025). Multivariable analysis demonstrated an increased risk of readmission for patients not treated with intravenous pulse methylprednisolone (IVMP) (OR = 17.5 (1.81-168.32) p = .013), and for those who required intravenous albumin assisted diuresis for hypervolemia (OR=6.25 (1.29-30.30) p = .022).

CONCLUSION

In all, 17% of children hospitalized due to new onset lupus nephritis were readmitted within 30 days of discharge. Absence of IVMP and receiving intravenous albumin assisted diuresis during initial hospitalization increase the risk of early readmission in new onset pediatric lupus nephritis.

Incidence and Risk Factors for 30-Day Readmission after Inpatient Chemotherapy among Acute Lymphoblastic Leukemia Patients

Chemotherapy for acute lymphoblastic leukemia (ALL) patients is complex and intense, resulting in a high readmission rate. We aimed to identify the incidence, causes, and risk factors of readmission following inpatient chemotherapy among ALL patients, using 2016 National Readmission Database. We applied three different definitions of 30-day readmission: (1) nonelective readmission based on readmission type, (2) unplanned readmission defined by CMS, and (3) unintentional readmission, combining (1) and (2). We used unweighted multivariable Poisson regression with robust variance estimates for risk factors analysis, including patient-, hospital-, and admission-related characteristics. Percentage for nonelective, unplanned, and unintentional readmission were 33.3%, 22.4%, and 18.5%, respectively. The top three causes for unplanned readmissions were neutropenia/agranulocytosis (27.8%), septicemia (15.3%), and pancytopenia (11.5%). Risk ratios for unintentional readmission were 1.21 (1.08–1.36) for nonelective vs. elective admission, 1.19 (1.06–1.33) for public vs. private insurance enrollees, 0.96 (0.95–0.98) for each day of hospital stay, 0.77 (0.62–0.95) for large teaching and 0.87 (0.70–1.08) for small teaching vs. nonteaching hospitals. Possible strategies to reduce readmission among ALL patients could be shortening the gap in quality of care among teaching vs. non-teaching hospitals, understanding the difference between privately vs. publicly insured patients, and avoiding aggressive discharge after chemotherapy.

Risk factors associated with paediatric unplanned hospital readmissions: a systematic review

OBJECTIVE

To synthesise evidence on risk factors associated with paediatric unplanned hospital readmissions (UHRs).

DESIGN

Systematic review.

DATA SOURCE

CINAHL, EMBASE (Ovid) and MEDLINE from 2000 to 2017.

ELIGIBILITY CRITERIA

Studies published in English with full-text access and focused on paediatric All-cause, Surgical procedure and General medical condition related UHRs were included.

DATA EXTRACTION AND SYNTHESIS

Characteristics of the included studies, examined variables and the statistically significant risk factors were extracted. Two reviewers independently assessed study quality based on six domains of potential bias. Pooling of extracted risk factors was not permitted due to heterogeneity of the included studies. Data were synthesised using content analysis and presented in narrative form.

RESULTS

Thirty-six significant risk factors were extracted from the 44 included studies and presented under three health condition groupings. For All-cause UHRs, ethnicity, comorbidity and type of health insurance were the most frequently cited factors. For Surgical procedure related UHRs, specific surgical procedures, comorbidity, length of stay (LOS), age, the American Society of Anaesthesiologists class, postoperative complications, duration of procedure, type of health insurance and illness severity were cited more frequently. The four most cited risk factors associated with General medical condition related UHRs were comorbidity, age, health service usage prior to the index admission and LOS.

CONCLUSIONS

This systematic review acknowledges the complexity of readmission risk prediction in paediatric populations. This review identified four risk factors across all three health condition groupings, namely comorbidity; public health insurance; longer LOS and patients<12 months or between 13-18 years. The identification of risk factors, however, depended on the variables examined by each of the included studies. Consideration should be taken into account when generalising reported risk factors to other institutions. This review highlights the need to develop a standardised set of measures to capture key hospital discharge variables that predict unplanned readmission among paediatric patients.

Factors associated with a prolonged hospital stay during induction chemotherapy in newly diagnosed high risk pediatric acute lymphoblastic leukemia

BACKGROUND

High Risk (HR) or Very High Risk (VHR) acute lymphoblastic leukemia (ALL) treated with 4 drug induction chemotherapy is often associated with adverse events. The aim of this study was to identify risk factors associated with a prolonged inpatient length of stay LOS during induction chemotherapy.

PROCEDURE

Data from patients (N = 73) (age<21 years) was collected through a retrospective chart review. Univariable and multivariable logistic regression was used to test for statistical significance. The overall survival and disease (leukemia)-free survival were analyzed using the Kaplan-Meier method and log-rank test.

RESULTS

Of the 73 patients, 42 (57%) patients were discharged on day 4 of induction (short LOS, group A), while 31 (43%) patients (group B) experienced a prolonged LOS or an ICU stay (16 ± 27.7 days, median hospital stay = 8 days vs 4 days (group A), p = 0.02) due to organ dysfunction, infectious or metabolic complications. Group B patients were more likely to have a lower platelet count, serum bicarbonate, and a higher blood urea nitrogen (BUN) on day 4 of treatment (OR = 4.52, 8.21, and 3.02, respectively, p < 0.05). Multivariable analysis identified low serum bicarbonate (p = 0.002) and a platelet count<20,000/μL (p = 0.02) on day 4 of induction to be predictive of a prolonged LOS. Twenty six (group A (n = 16, 36%) and B (n = 11, 35%), p = 0.8) patients experienced unplanned admissions, within 30 days of discharge.

CONCLUSIONS

A significant proportion of newly diagnosed HR or VHR pediatric ALL patients experience a prolonged LOS and unplanned re-admissions. Aggressive discharge planning and close follow up is indicated in this cohort of patients.

Quality and safety in pediatric hematology/oncology

Many principles of quality of care and patient safety are at the foundation of pediatric hematology/oncology. However, we still see too many errors, continue to have problems with communication, and the culture in many of our areas is still one of worrying about retribution when mentioning a problem. This review explores why specialists in pediatric hematology/oncology should be leaders in the field of quality and safety in healthcare.

Severe neutropenia at time of port insertion is not a risk factor for catheter-associated infections in children with acute lymphoblastic leukemia

BACKGROUND

The objective of this study was to determine whether severe neutropenia on the day of port-a-catheter (PORT) insertion was a risk factor for catheter-associated infection (CAI) in children with acute lymphoblastic leukemia (ALL).

METHODS

This was a retrospective study of children with ALL who had a PORT insertion between January 2005 and August 2008. Early (≤ 30 days) and late (>30 days) postprocedure complications were reviewed. The length of follow-up ranged between 7 months and 42 months.

RESULTS

In total, 192 PORTs were inserted in 179 children. There were 43 CAIs (22%), and the infection rate was 0.35 per 1000 catheter-days. The CAI rate (15%) in children who had severe neutropenia on the day of the procedure did not differ statistically from the CAI rate (24%) in children who did not have severe neutropenia (P = .137). Conversely, patients with severe neutropenia who had a CAI were more likely to have their PORT removed (P = .019). The most common organisms to cause catheter removal were coagulase-negative Staphylococcus and Staphylococcus aureus. Patients with high-risk ALL had a statistically significant higher incidence of late CAI than patients with standard-risk ALL (P = .012). Age (P = .272), positive blood culture preprocedure (P = 1.0), and dexamethasone use (P = .201) were not risk factors for CAI. Patients who had an early CAI did not have a greater chance of having a late CAI. The catheter infection-free survival rate at 1 year was 88.6%.

CONCLUSIONS

The current results indicated that severe neutropenia on the day of PORT insertion does not increase the risk of CAI in children with ALL.
